At around 280W, the 9070 powercolor reaper flashed into XT performs around 22% faster on benchmarks, and 17% faster in rasterized games and 14% faster when ray tracing is on. -105mv undervolt, and 2800mhz default timings. (these are stable numbers that I was gaming on past 3 months on this GPU)
These tuning profile normally only allowed 5-10% gains in games, and 10% gains on steelnomad. Feeding GPU 40W more furthermoremore than doubled the performance.
Note, these results are based on 0% power limit, if I increase it to 10%, it runs at 340W, but there is no benefit in performance in games, and only 200 points increase on steel nomad. So I settled down at 280W meaning -5% powerlimit.
I increased the fan speeds around 5-10% thus core and memory temps are nearly identical, 2-3C difference, but hotspot is 5C hotter.
(it is 10C hotter on the images because after taking photos, I found out that at 280W the performance was identical but hotspot dropped big time, so keeping it at there)
Holly smokes I am really impressed.
